Ratcheted Toilet Seat and Lid

ABSTRACT

The present invention provides a toilet comprising a locking component that locks a toilet component (e.g. a toilet seat or toilet lid) in an open, closed, or intermediate position. The holding or locking of the toilet component can be provided by a hinge, a spring, or some other appropriate manner.

This application claims the benefit of U.S. provisional application No. 60/476,070 filed on Jun. 4, 2003 incorporated herein by reference in its entirety. Additionally, this application is a Continuation in Part of U.S. patent application Ser. No. 10/860,264 filed on Jun. 2, 2004.

FIELD OF THE INVENTION

The field of the invention is toilet seats.

BACKGROUND OF THE INVENTION

It has been observed that, for a typical toilet seat or lid, raising it less than 90 degrees and then releasing it will result in the seat/lid crashing down against the bowl or seat of the toilet. This poses a safety hazard in that the force of the seat/lid crashing down can hurt someone having a finger or other body part caught between the seat/lid and the bowl/seat. Even if no one gets hurt, the noise of the seat/lid closing can be an annoyance.

There is a need for toilet seats that address these problems.

SUMMARY OF THE INVENTION

The present invention provides a toilet comprising a locking component that locks a toilet component (e.g. a toilet seat or toilet lid) in an open, closed, or intermediate position. The holding or locking of the toilet component can be provided by a hinge, a spring, or some other appropriate manner.

It is contemplated that toilet seats and lids may be improved by (a) using bumpers to cushion the contact between the seat and lid, and (b) using a hinge adapted to prevent the seat and/or lid from returning to its closed/down position without being pushed down or otherwise manually released.

In an exemplary embodiment of the present invention a toilet comprising a locking component that locks a toilet component in an open, closed or intermediate position is disclosed.

In an exemplary embodiment, a toilet seat is disclosed wherein the toilet seat has bumpers coupled to a lid.

In an exemplary embodiment, a toilet seat is disclosed wherein the toilet component is a seat.

In an exemplary embodiment, a toilet seat is disclosed wherein the toilet component is a lid.

In an exemplary embodiment, the bumpers are comprised of rubber.

In an exemplary embodiment, the locking component has a hinge assembly.

In an exemplary embodiment, the hinge assembly has ratchets.

In an exemplary embodiment, the hinge assembly has a spring.

In an exemplary embodiment, the toilet seat has a release mechanism that releases the toilet component from the open, closed or intermediate position.

Various objects, features, aspects and advantages of the present invention will become more apparent from the following detailed description of preferred embodiments of the invention, along with the accompanying drawings in which like numerals represent like components.

DETAILED DESCRIPTION

Referring first to FIG. 1A, a toilet 100 comprises a lid 110, a seat 120, a bowl 130, and a hinge assembly 140. Lid 110 comprises pivot arms 111A and 111B, and bumpers 112. Seat 120 comprises pivot arms 111A and 111B. Hinge Assembly 140 comprises end caps 141A and 141B, center assembly 142 and pin 143.

Lid 1 10 may be any type of toilet lid but is preferred to include resilient bumpers 112, and to have pivot arms 111A and 111B adapted to interact with hinge assembly 140. Hinge assembly 140 functions to lock the lid which means that the lid may be lifted (rotated away from the bowl 130) and released without the force of gravity pulling it back against seat 120. The bumpers are preferably constructed of rubber but other suitable materials include plastics, metals, and so on.

Seat 120 may be any type of toilet seat but is preferred to have pivot arms 121A and 121B adapted to interact with hinge assembly 140 such that the seat is upwardly biased. It should be understood that both the seat and the lid may be locked by utilizing a locking component 151 in an open, closed or intermediate position, but in preferred embodiments, it is the seat that is locked. It should also be noted that in some less preferred embodiments only the lid will be adapted to be positioned (positionable) in the manner described above while in others only the seat will be so positionable. For the sake of clarity, much of the remainder disclosure will discuss only the lid as it would be clear to one of average skill in the art that the features described may be and preferably will be equally applicable to toilet seats as well.

It is contemplated that in some embodiments it may be desirable to include a release mechanism 149 in hinge assembly 140 to allow the lid to move freely up and down. in other embodiments the release mechanism 149 may be needed to change the position of the lid. In those other embodiments, without actuation of the release mechanism 149, the lid: i) cannot be moved from a closed to an intermediate or open position; ii)cannot be moved from an intermediate position to an open or closed position or another intermediate position; and iii) cannot be moved from an open position to an intermediate or closed position.

As depicted in FIG. 1 B, it is contemplated that hinge assembly 140 may be adapted to allow end caps 141A and 141B to be pulled away from center assembly 142 (and the pivot arms 111A, 111B, 121A, and 121B) in order to release the lid. Springs 159 may be used to bias the end caps in a non-release position. In alternative embodiments, the hinge assembly 140 which may comprise a locking component 151 that locks the seat in a closed, opened, or intermediate position. It will be understood by one of ordinary skill in the art that locking component 151 may be achieved at least partially by using a hinge and/or spring 159 as well as other known techniques.

FIGS. 2A-2D show four (4) positions of lid 110 in which lid 110 forms an angle (A1-A4) of less than 90 degrees with seat 120 and rim 131 of bowl 130. In preferred embodiments lid 110 will be positionable to any angle at least less than or equal to 90 degrees. In less preferred embodiments, lid 110 may be positionable to a finite set of positions where the total number of positions is at least three (i.e. closed or 0 degrees, open or approximately 90 degrees, and an intermediate position where the angle is between 0 and 90 degrees). The locking component 151 may comprise any mechanism that allows lid 110 to be positioned in such a manner.

FIGS. 3A-3C illustrate some of the essentially infinite possible relationships between lid position and the force required to move the lid further up or down. In. FIG. 3A, the force required to move the lid does not change depending on the current position of the lid or whether the lid is moving up or down. In FIG. 3B, the force required to move the lid up is less than the force required to move the lid down, regardless of current seat position. In FIG. 3C, the force required to move the lid up is always equal to the force required to move it down regardless of the current position of the lid, but the force required varies between positions. It is contemplated that in some instances it may be desirable to increase the amount of force required to move the lid as the lid approaches its closed position while in others the reverse may be true.

In FIG. 3C, the force required to move the lid up is always equal to the force required to move it down regardless of the current position of the lid, but the force required varies between positions. It is contemplated that in some instances it may be desirable to increase the amount of force required to move the lid as the lid approaches its closed position while in others the reverse may be true.

Thus, specific embodiments and applications of a ratcheted toilet seat and lid have been disclosed. It should be apparent, however, to those skilled in the art that many more modifications besides those already described are possible without departing from the inventive concepts herein.
